Batch wallet snapshots for multiple Base addresses in one paid call, all anchored to a single block: native and ERC-20 balances, account flags, and derived metrics per address. Efficient multi-wallet portfolio and balances lookup for AI agents.

Day-trade counter for trading agents: matched same-day buy/sell pairs per symbol in the rolling five-trading-day window (versioned NYSE holiday calendar), total in-window trades, and the ratio — with FINRA's pattern-day-trader definition (Rule 4210) cited separately as a published fact. Counts only, never a status determination; the comparison belongs to the caller. Nothing is stored.

DeFi position and wallet risk snapshot on Base: token balances, account flags, and live Aave v3 collateral, debt, borrowing power, and health factor read directly from the protocol at a specific block, plus derived risk metrics — net equity, LTV utilization, leverage multiplier, health-factor band, and collateral drawdown tolerance (how far collateral can fall before liquidation). For agents assessing portfolio exposure and liquidation risk.

x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.

Batch x402 endpoint reliability: factual delivery measurements (uptime, valid-402 rate, latency, last status) for an agent's whole tool list of x402 endpoints in one paid call. Sweep every endpoint you depend on before relying on them. Facts only — not an endorsement or rating.

Trade-lot holding-period and realized-gain calculator for trading agents: per-lot days held, the exact date each lot's gain character turns long-term, and FIFO / specific-identification allocation of a proposed sell with realized gain per lot and per-character totals. Deterministic arithmetic on caller-supplied lots with the published threshold cited (IRC §1222: held more than one year) — counts, dates, and dollars only, never advice. Nothing is stored.

T+1 settlement-date calculator for trading agents: the settlement date for each caller-supplied equity trade and whether it has settled as of a given date, on the versioned NYSE holiday calendar, with SEC Rule 15c6-1 cited as a published rule. Dates and counts only, never a violation determination. Nothing is stored.

On-chain wallet snapshot on Base: native ETH and tracked ERC-20 token balances (USDC, WETH) plus account flags (contract status, transaction count) and derived metrics (wallet type, activity tier, gas runway), anchored to a specific block. Factual wallet balance and holdings lookup for AI agents — portfolio and on-chain data API.
